Broadcom Unveils Industry’s First 11mm SSO-8, 5A/3A Gate Drive Optocouplers
Published: Nov 09,2016422 Read
Broadcom Limited announced a new family of 5A and 3A gate drive optocoupler devices, the Avago ACNU-3430 and ACNU-3410, respectively. The devices are the first 5A and 3A gate drive optocouplers offered in the 11mm SSO-8 package for high voltage, space constrained industrial applications including 600VAC motor drives and 1kVDC solar inverters.

Broadcom Announces Industry’s First Silicon-Proven 7nm IP for ASICs in Deep Learning and Networking
Broadcom today announced the industry’s first silicon-proven 7nm intellectual property (IP) for an ASIC platform targeting deep learning and networking applications...
The new package platform features wide creepage and clearance, high insulation voltage and a compact package footprint, providing enhanced high voltage protection and signal isolation in tight spaces.
In comparison with the market-proven Avago HCNW3120 gate drive optocoupler offered in the 400mil DIP-8 package, the ACNU-3430 and ACNU-3410 are 40% smaller in size and have higher peak output current and wider creepage and clearance.
The new devices have higher common mode transient immunity (CMTI) exceeding 100 kV/µs to help prevent erroneous gate driver failures in harsh, electrically noisy environments. Furthermore, the new devices have one third (1/3) the propagation delay, enabling high frequency switching to improve efficiency in driving IGBT and SiC/GaN MOSFET.
